Did the sampling frequency changed over the years?

I'm working on identifying the falling and rising edges of the VAL_23-KA-9101-M01:HSI.StatusMotorOn signal. For that and shifting the TS and rest the values, if I get -1 is a falling edge and for 1 it is a rising edge. For the first row it works fine: But I’m also getting a lot of values different than 1 or -1. Especially for more recent years. I guess that the problem is at the aggregating step, since I downloaded the data at a 1m frequency I get not int values for some records. Now, I was trying to download this TS at a 1s frequency, but I get a different number of records depending on the year. E.G. for 2014 I get 34 records for a 10 days time windows with a granularity 1m. If I do the same but for 2020 I get 1411, much more than for 2014, but still a tenth of the expected count. If I change the granularity to 1s, I still get the same number of records, but with more precision in the time stamp: Considering this, is there a recommended granularity to download the data and min

Cognite Data Fusion: ChartsPlanned for development

Celanese - CriticalThe ability to overlay other transactions on time series data or create time series from transcations is necessary when troubleshooting. For example, i might be analysing several time series tag and i would like to plot work order and notification dates and/or other events on the same plot. This will really help us do better Root Cause Analaysis.

In CDF, we have a back button - need a forward buttonGathering Interest

There is the arrow on the left hand side of the screen for CDF to go backwards. Please add a corresponding arrow to return to the screen from which you just went back. Makes navigating back and forth between data very easy.

Different types of edges connecting nodes in FDMUnder construction

Hi, So far, I have the understanding that you can add edges between nodes, however, not different type of edges.In a watercourse, one would have several hydro power plants, reservoirs, etc.. and different water routes and flood routes connecting these objects (nodes). These connections would be of different type of edges, which seems to be a lacking feature in FDM if I am correct. Having this function available in FDM would be helpful in developing a data model for our water courses :)

InField - Filter on state in checklistGathering Interest

Entered on behalf of Celanese VAM Unit InField SuperuserAs a shift Captain I would like the option to filter for only Not Ok within the checklist before I approve it. I am only interested in reviewing those items and address them as needed. This will save time and human error from scrolling to find the Not OK ones (and see the comments and images attached. You should be be able to filter on any one of the states (e.g. To Do, N/A, OK, Not OK, etc)

Can the signals of warnings, alarms, and failures be used to tag anomalies and/or failures in the compressor?

There are some signals that in the names or the description have the words: alarm, warning, or fault. E.G. There is this alarm signal, (in red ) that I’m comparing with one of the vibration signals. And the alarm seems to be on when the vibrations are close to 0 and the Compressor is off. I’m plotting the label as a combination of the name and the description, but the externalId of the alarm is: pi:160268In most cases that alarm is on when the compressor is off, except in this case, Where I do not see any problem with the vibration signal: There are these other two alarms, from the plots: one is on when the compressor is off and the other one when it is starting up. But I do not see any strange behavior in the signal when they occur. Besides the alarms, I’ve also looked into some of the fault signals but those seem to be on for very long times: Is there another way to use the alarm and fault signals to label anomalies or failures? I don’t know if using the vibration signals is the bes

Relationships in powerbi

HiI have retrieved timeseries from an asset in PowerBi. That asset is linked through a relationship column to a group of assets. However the asset and the group it belongs to are connected trough 4 steps:groupwanted <- belongsTo - subgroup<- belongsTo - type of group <- connectsTo - group of a few timeseries assets<- belongsTo - timeseries asset Im wondering how to link the relationships in power bi, and how to orient to the right place.

Wildcard listing resources

I am listing time series for a given asset, and get a lot of results. I need to filter based on the time series external ID, but the only option is by using the “external_id_prefix” argument to the list function. So I build up the prefix left to right. Somewhere in the external id is a parameter that I do not care about, and after comes a new parameter that I want a particular value of. Concrete example of external IDs:IAA_Miros_Weather_Data_WIA_008IAA_Miros_Weather_Data_WIB_008IAA_Miros_Weather_Data_WIC_008IAA_Miros_Weather_Data_WID_008IAA_Miros_Weather_Data_WIE_008I am interested in only getting time series with external IDs that contain “_WI” and that end with “008”. Is there a way to list time series with a wildcard? Something like this:client.time_series.list( asset_ids=[my_asset_id], limit=None, external_id_prefix="IAA_Miros_Weather_Data_WI*_008", partitions=4)I could of course obtain the relevant time series by filtering after the fact. Something like thisresult = cl

Whitelisting of Elastic-queries

Hi!Almost three years ago we made a feature request regarding search. Specifically we want to:Have support for paging. Do grouping on metadata-fields. Define which fields yields relevance to the search-results. Inclusive search-terms using AND instead of OR.I do understand that satisfying the search-requirements of all your users is a daunting task, but perhaps it would be easier to let us do the job instead? I believe it would be very beneficial if we were able to access ElasticSearch directly in some manner.And please keep in mind that the data itself defines relevancy. No two customers are alike and therefore a good generic solution likely doesn’t exist. @Knut Vidvei @Andreea Pastinaru

Charts

Remote App - Time Series trend window, cursor detail items window, tag name too short, value has > 10 decimal places.

I was looking at trends in the Remote App web version, using the cursor to touch tags. The detail pane shows the tag name(s) and current value where the cursor x axis crosses. The issue is the tag names are cutoff and mostly unreadable, the tag value is showing almost 10 or more decimal places. I would like to see the whole tag name and 1 or 2 decimal places, or use the signficant digits from the PI Server in the first place.
